JPMorgan exec Bisignano departs

Frank Bisignano, who was co-chief operating officer at JPMorgan, is leaving the bank to run First Data Corp., a payments processing firm.

Another one of Jamie Dimon's key executives is leaving JPMorgan Chase, the firm announced Sunday.

Frank Bisignano, co-chief operating officer along with Matt Zames, is leaving the bank to run First Data Corp., a payments processing company owned by private equity firm KKR. Zames, who now appears to be the clear frontrunner to lead JPMorgan (JPM) when Dimon retires, will be the sole COO of the bank.

"I am pleased that Matt Zames is expanding his role," Dimon said in a statement. "He is a proven business executive, who has performed exceptionally well since coming into his corporate role in May of last year."
